Across
  1. 3. process by which solids are ingested by living cells; it is another type of endocytosis
  2. 4. process of diffusion in which molecules pass across the membrane through cell membrane channels
  3. 6. when comparing two solutions, the solution with the greater concentration of solutes
  4. 8. thin, flexible barrier that surrounds all cells; regulates what enters and leaves the cell
  5. 9. a microscope with high magnification that uses electron beams in place of light
  6. 10. cellular transport where substances move against a concentration gradient. (requires energy)
  7. 13. group of tissues that work together
  8. 17. organism whose cells contain a nucleus
  9. 19. the process by which cells move materials out of the cell
  10. 20. cell organelle that stores materials such as water, salts, proteins, and carbohydrates
  11. 21. groups of cells that work together (same job)
  12. 22. unicellular organism that lacks a nucleus
  13. 23. network of protein filaments in a eukaryotic cell that gives the cell its shape and internal organization and is involved in movement
  14. 25. the process by which cells move materials from within the cell into the extracellular fluid
  15. 26. microscope that uses multiple lenses and light to enlarge the image of a sample
  16. 27. cells can develop in different ways to have different features to help them carry out a special task to help the organism function
Down
  1. 1. cell organelle that breaks down lipids, carbohydrates, and proteins into small molecules that can used by the rest of the cell
  2. 2. process by which particles tend to move from an area where they are more concentrated to an area where they are less concentrated
  3. 5. property of biological membranes that allows some substances to pass across it while others cannot; also called semi permeable membrane
  4. 7. when comparing two solutions, the solution with the lesser concentration of solutes

  7. 12. diffusion of water through a selectively permeable membrane
  8. 14. tiny sacs that transport material within or outside the cell
  9. 15. basic unit of life
  10. 16. a process by which liquid droplets are ingested by living cells; it is one type of endocytosis
  11. 18. when the concentration of two solutions is the same
